ALZO Pan-L-Lites are ideal for use in small video productions where soft light is preferred and ultra fast setup is essential. ALZO Pan-L-Lites are the only fluorescent dimmable video lights to employ linear slide dimmers. Slide dimmers are an improvement over rotary dimming because visual reading of the intensity setting is greatly improved and it is easy to repeat a setting with high accuracy. In addition, ALZO Pan-L-Lites dimmers include intensity markings that are important for repeating light ratios. All ALZO Pan-L-Lites include a removable honeycomb filter that is essential for changing the cast and hardness of the light. Without the honeycomb the light is a very broad soft light. When the honeycomb is added, the light is reduced in beam spread to about 40 degrees, and it will reduce the intensity of the light as well. This makes the light slightly focused and harder, increasing the shadow contrast. In addition, the honeycomb can be stacked using gaffer tape to increase the focus and hardness of the light. The honeycomb is an important creative light control modifier that we include with ALZO Pan-L lights. These lights are really cool and produce a fraction of the heat of conventional continuous hot lights, and they have low power consumption. The ALZO Pan-L-Lites use flicker-free electronic ballasts and ALZO Video-Lux light tubes for perfect color mixing with daylight or Tungsten. The tubes have a very long life of about 8,000 hours. The integral barndoors can be folded flat over the honeycomb filter, thus protecting the tubes and making it very handy for transporting (briefcase-style).
